Abstract
The invention provides a curved metal plate forming process. The process includes the steps: preparing 6 carbon steel tooling plates matched with raw metal plates, regularly stacking 1-300 raw metal plates with the thickness of 1-300mm on a bottom tooling plate, and tightly clamping the stacked raw metal plates by a front tooling plate, a rear tooling plate, a left tooling plate and a right tooling plate; pressing the clamped raw metal plates by a hydraulic press, welding the bottom tooling plate with the front tooling plate, the rear tooling plate, the left tooling plate and the right tooling plate to from a tooling box, covering a top tooling plate, and pressing the top tooling plate and the raw metal plates once more prior to welding the top tooling plate with the front tooling plate, the rear tooling plate, the left tooling plate and the right tooling plate; after the tooling box is made, placing the tooling box and the raw metal plates on an intermediate-frequency machine, and heating while integrally bending the raw metal plates to curved plates; after bending, subjecting the tooling box and the curved metal plates to air cooling; performing stress-relief heat treatment; and after the tooling box and the curved metal plates are cooled completely, detaching the tooling plates, and taking out the formed curved metal plates. The process is easy for formation quality control, energy-saving and environment-friendly, more than 30% of raw materials are saved, and production efficiency is improved greatly by the aid of batch forming.
Description
Technical field
The present invention relates to the circular arc molding technique of metallic plate, particularly a kind of moulding process of metal arc.
Background technology
In order to comply with the demand in market, now a lot of equipment all adopt special material to make.Arc in the equipment by after the steel plate cutting, carries out machined usually again, the processing technology more complicated, and this forming method, although simple, material is slatterned in a large number.
Summary of the invention
The objective of the invention is for arc in the prior art by after the steel plate cutting, carry out again the weak point of machined moulding, the designer has adopted a kind of moulding process of metal arc, this moulding process operation is simple, and Forming Quality is controlled easily, and energy consumption is low, save raw material, operating environment is good, is easy in batches moulding, greatly enhances productivity.Produced thus useful technique effect, and practical value is higher.
The present invention is achieved in that the moulding process of a kind of metal arc of the present invention, realizes through the following steps:
(1) with the raw metal plate of thickness 1～300 ㎜, cut growth 1000～2000 ㎜, wide 50～300 ㎜ strip raw metal plates;
(2) prepare 6 carbon steel working plates that are complementary with the raw metal plate by the length size of 1～300 block of raw metal plate: frock top board, frock base plate, front working plate, rear working plate, left working plate, right working plate, wherein frock top board, frock base plate, front working plate and rear working plate length are that 1500～2200mm is used as the medium frequency equipment clamping;
(3) 1～300 metal lot raw material plate is neatly superposeed, be placed on the frock base plate, with hydraulic press with its upper-lower compacting, avoid the space between plate and the plate, then use front working plate, rear working plate, left working plate and right working plate clamp the raw metal plate after the stack, after the compression with frock base plate and front working plate, rear working plate, left working plate, right working plate welding, front working plate, rear working plate and left working plate, right working plate is welded to each other and forms the frock case, cover the frock top board, last hydraulic press is again with after frock top board and the folded face compression of raw metal plate, with frock top board and front working plate, rear working plate, left working plate and the welding of right working plate;
(4) after the frock case is made, be put on the medium frequency equipment with the raw metal plate, promote the frock case and advance at the medium frequency equipment track, on one side heating, its Integral bending is made R300～3000 ㎜ arc plates on one side;
(5) bend after, frock case and metal arc are cooled off in air;
(6) behind the air cooling, with the heat treatment that eliminates stress of frock case and metal arc;
(7) after cooling off fully, remove working plate shape, take out in type metal arc;
Raw metal plate thickness of the present invention is 1～300 ㎜, stack height 1～300 ㎜.
Working plate of the present invention is to be made by carbon steel material, and thickness is 18～25 ㎜.
The present invention compared with prior art has following advantage:
1, for metal, the utilization rate of material is very important, and the present invention improves the utilization rate of material greatly.The present invention compares with other circular arc molding methods, can save 30% above metal material.
2, the stack of this circular arc molding process using steel plate bends, and is little with the forming errors of batch arc, is easy to guarantee Forming Quality.
3, the frock material is made of carbon steel or steel scrap, has reduced manufacturing cost.
4, energy consumption is low, operating environment is good, because in batches moulding is greatly enhanced productivity.
